Bilstein B6 vs B4 longevity and ride quality?
Some people claim that the monotube designs on the B6 should last longer than B4’s twin tube, but realistically how much difference in longevity is there? I would be keeping the stock M sports suspension springs. This is on an E85 3.0si; the upper strut mounts and boots are all going to be replaced as well. Am I going to regret the stiffness of the B6?
